Bevel Buddy Manual

Bevel Buddy™ Instruction

We at Precision Sharpening Devices Inc. believe there are two very important steps in maximizing the savings this equipment can provide your company. First, use this manual to educate your operators in the proper set-up and operation of this equipment. Second, plan to keep the knives sharp at all times. Do not let the knives go beyond the resharpening point. A chipper is no better than the knife edge itself. We always invite your questions and comments concerning our products. We feel that these innovative resharpening devices will help you remain competitive in the wood processing industry.

1. Safety Instructions READ BEFORE USING

• Do not expose this sharpener to rain or wet conditions.

• ALWAYS remove the battery from the tool or disconnect from the power source before making any adjustments or changing / indexing the abrasive, and storing the sharpener in the supplied storage case.

• When the battery pack is not in use, do not store it around any loose metal objects, keep it in the storage box.

• If the battery ever has leakage, remove it from use and replace it with a new one.

• DO NOT store the sharpener or the battery in temperatures below 32º or above 113º Fahrenheit, battery or motor damage may occur. Charge the battery pack in temperatures between 32º and 113º Fahrenheit only as well. Please recycle your dam-aged or worn out batteries at a certified recycling center.

• ALWAYS wear safety glasses when the sharpener is in use and avoid breathing the grinding dust associated with the resharpening.

• ALWAYS lock out the chipper drive motor to ZERO ENERGY STATE before resharpening the knives.

• NEVER force the resharpener into a work area, always ease into the knife sharpening.


2. Type of machine the sharpener is being used on and which abrasive to use for that set-up.

When using our resharpeners you must ALWAYS counter grind / back bevel on the side of the knife that the material discharges from only!! NEVER attempt to resharpen the feed side of the knife!

Pocket mounted knife for disc style chipper, use drum style abrasive #A-MDA0195-D80. Note: Roller position and abrasive contact to knife. FOR KNIVES BETWEEN 29º TO 36º
Drum style chipper knife, use drum style abrasive #A-MDA0195-D80. Note: Roller position and abrasive contact to knife. FOR KNIVES BETWEEN 29º TO 36º
Face mounted style knife, use drum style abrasive #A-MDA0195-D80. Note: Roller position and abrasive contact to knife. FOR KNIVES BETWEEN 29º TO 36º
Plywood lathe knife set-up, use cone style abrasive #A-MDA0197-C80 with large diameter of abrasive away from the drive motor. FOR KNIVES BETWEEN 22º TO 25º
Pole Peeler or some small chippers knife set-up. Use cone style abrasive. #A-MDA0197-C80 with large diameter of abrasive toward the drive motor. There may be times on this more blunt angle style knife when you need to make a minor adjustment on the top roller bracket opening (#2 spring loaded bracket.) Using a pair of pliers slightly bend each side outward, 1/16” at a time until proper abrasive knife contact is achieved. FOR KNIVES BETWEEN 42º TO 45º
Disc chipper modified set-up, there may be times on a disc chipper set-up when a knife is shortened to make a smaller chip like those used in pellet manufacturing. The universal grinding head may come in contact with the disc wear plate. In this set-up you must do two things: Use the cone style abrasive #A-MDA0197-C80 with the large end away from the drive motor. Then you may have to tune the lower set of rollers by bending them away from or back towards the drive motor approximately 3/16” to 1/4” making sure they are both bent at the same angle. This will allow the motor mount to move away from the disc wear plate.

3. Proper Operating Procedures

• Before using the Bevel Buddy Resharpener make sure the proper abrasive for the task is applied to the resharping tool, refer to section 2 for the set-up.

• When performing the resharpening process on the knife, as you are facing the disc and it turns counter clockwise start the sharpening process from your right and move to the left. On a clockwise rotating disc, start the sharpening process an your left and move to the right.

• Apply very little pressure on the sharpener to knife edge. The diamond abrasive is very aggressive, so to avoid over grinding always keep sharpener in motion while sharpening the knife. One pass per knife is usually sufficient per sharpening. *REMEMBER let the abrasive do the work!

• The counter ground path on the back of the knife should be approximately 1/16” to 1/8” wide.

• We suggest resharpening the knives in the chipper no more than 3 times before removing them to be sharpened in your stationary grinder or reversed on a turn knife system.

• Drive motor operating speed for the Bevel Buddy™ Max:
▫ 12 volt battery sharpener must be started in low speed. You then increase it to high speed, sharpen your knives, then decrease back to low speed to turn it off.
▫ 12 volt charger green light will be blinking while the battery is charging and on solid green when the battery is fully charged.
▫ 12 volt corded— ON / OFF switch
▫ 120 volt — ON / OFF switch

• Clean grinder head weekly. (Blow off with compressed air only)


4. Abrasive Indexing Procedure

When the abrasive becomes worn on the drum or cone area, the drive motor can be adjusted back to a fresh area for proper sharpening.

A.) Loosen the thumb screw on the sharpener head.

B.) Hold universal grinding head and turn the drive motor counter clockwise 180º or 1/2 turn.

C.) Snug set screw slightly to lock the head and motor, this will give you a new abrasive area to sharpen your knives.

D.) This indexing procedure can be performed 3 times before the abrasive must be replaced.

E.) Make sure your sharpener is in the zero energy state—unplugged from power source.

F.) To replace the abrasive: Remove the battery from the drive motor or disconnect the drive motor from the power source. Loosen the locking set screw, turn the drive motor counter clockwise to remove the universal grinding head. Hold the spindle lock button down and twist the abrasive clockwise to remove it. Reverse the procedure to attach the new abrasive.

G.) When threading the drive motor back into the universal grinding head, make sure you DO NOT cross thread it. The motor threads are plastic.
